So you got it working? Ye growl need to run its the program that shows notifications. If you wanna hide the CMD window from server.py you can just make a bat-file containing "python c:\path\to\file\server.py" then make a .vbs file containing : then you run the .vbs file and it should run the bat file with no window. thats what i did since i failed with making a service of the .py file with AnySrv, it just started and stopped lol, well well it works atleast. And on N900 theres alot of ways to run stuff in background. a noob-friendly and simple way is to use the "nohup client.py &" command
